DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18216776 titled 'DISPLAY DEVICE

Simplified Explanation

The patent application describes a display device with an auxiliary electrode structure that includes metal layers stacked in an undercut configuration, along with a light-emitting element layer. The auxiliary electrode has bonding portions that make contact with the common layer and common electrode, facilitating the operation of the device.

• The display device includes:
  • Substrate
  • Auxiliary electrode with metal layers in an undercut structure
  • Light-emitting element layer with a second common layer
  • Common electrode extending to the non-emission area

• The auxiliary electrode has:
  • First and second sides facing each other in one direction
  • Third and fourth sides facing each other in another direction
  • First bonding portion in contact with the second common layer
  • Second bonding portion in contact with the common electrode

• The first bonding portion has:
  • First width at a first point of the first side
  • Second width smaller than the first width at a second point of the third side

Potential Applications

The technology described in the patent application could be applied in the development of advanced display devices for various electronic products, such as smartphones, tablets, and televisions.

Problems Solved

This technology helps improve the efficiency and performance of display devices by enhancing the connection between the auxiliary electrode and the light-emitting element layer, resulting in better overall display quality.

What are the potential challenges in scaling up the production of display devices using this technology?

The patent application does not address the potential challenges that may arise when scaling up the production of display devices incorporating this new auxiliary electrode structure.

Original Abstract Submitted

A display device includes a substrate; an auxiliary electrode including metal layers stacked in an undercut structure; and a light-emitting element layer. The light-emitting element layer includes a second common layer; and a common electrode which extend to the non-emission area. A side surface of the auxiliary electrode includes a first bonding portion in contact with the second common layer, and a second bonding portion in contact with the common electrode. The auxiliary electrode includes a first side and a second side facing each other in one direction, and a third side and a fourth side facing each other in other direction crossing the one direction. The first bonding portion has a first width at a first point of the first side and has a second width smaller than the first width at a second point of the third side.
